TEFRO®cor 310 RP

Corrosion Protection Coating

TEFRO®cor 310 RP is a one-component anti-corrosion coating based on silane-terminated prepolymers. It cures with ambient moisture, so it bonds to damp, ice-free steel — even below the dew point — and protects to corrosion category C4 (DIN EN ISO 12944-4) in a single coat that combines primer and topcoat. Supplied by Trivaro across Europe and Scandinavia.

Built for conditions that defeat ordinary coatings

Moisture, frost and tight maintenance windows usually stop a coating job. TEFRO®cor 310 RP is engineered for exactly those conditions.

One component, no mixing

Applied straight from the bucket — no mixing ratio, no catalyst, no pot-life clock.

Bonds to damp steel

Moisture-curing and superhydrophobic: coat damp, ice-free steel below the dew point.

Single-coat C4

Primer and topcoat in one — 300 µm vertical / 500 µm horizontal dry film per coat.

UV-resistant

Weather-resistant and UV-stable, so it can be used without a separate UV topcoat.

All-season window

Works from −5 to +35 °C at any humidity — no viscosity jump in the cold.

Cleaner chemistry

Solvent-free; free of isocyanates, amines and epoxy resins (VOC approx. 10 g/L).

Where it is used

Steel assets in wet, salt-laden or chemically loaded environments — far beyond marine alone.

01

Marine, shipyards & ports

Steel structures in coastal and saltwater exposure, shipyards and port areas.

02

Water & wastewater

Sewage treatment plants and hydroelectric installations under constant moisture.

03

Energy & infrastructure

Power poles, pylons and structural steel exposed to weather year-round.

04

Tanks & fuel storage

Fuel depots and tank exteriors that need durable single-coat protection.

05

Transport & high-humidity buildings

Steel in transportation and humid structures such as swimming pools.

06

Industrial & chemical plants

Process equipment and structural steel exposed to aggressive, chemically loaded atmospheres.

Surface preparation & application

Two routes, depending on the specification.

  • Standard (ISO 12944)

    Sa 2½ blast cleaning, average roughness Rz ≥ 50 µm, free of mill scale, rust and grease.

  • Reduced preparation

    Remove loose adhesions only; apply on damp, ice-free steel below the dew point — by agreement with the client.

  • No standing water

    Dripping or liquid water on the surface to be coated is not permitted.

  • Roller build

    Approx. 100 µm DFT per pass by roller; smoother finish by spray.

  • Recoating

    Interval is unlimited; sweep-blast and lightly roughen if contaminated. Remove dust dry (no water).

  • Independent testing

    External test institute certificate available (ref. LAB21-0413).

Frequently asked questions

Key points specifiers ask before selecting a single-coat corrosion system.

Can it be applied to wet steel?

+

Yes — it is moisture-curing and superhydrophobic, so it bonds to damp, ice-free steel and even below the dew point. Standing or dripping water is not permitted.

What corrosion class does it reach?

+

Up to corrosion category C4 per DIN EN ISO 12944-4, as a single coat combining primer and topcoat.

Does it need mixing or a separate topcoat?

+

No. It is one-component, used straight from the bucket with no mixing ratio. It is UV-resistant and needs no additional UV topcoat.

What temperature and humidity range can it handle?

+

Working and substrate temperature −5 to +35 °C, at any humidity, including below the dew point on damp, ice-free steel.

Is it solvent-free and free of hazardous binders?

+

Yes — solvent-free (VOC approx. 10 g/L) and free of isocyanates, amines and epoxy resins.
